Amber Griswold slings (spiderlings) are pretty cheap, actually. Like, as low as $5.
Arachnoboards.com is a great resource if you want to get into the hobby. :)
SwiftInverts.com KenTheBugGuy.com CaptiveInverts.com and BugsInCyberspace.com are all great places to buy your first T.
if you're in the UK or Europe: check out JamiesTarantulas.com :)
